personaly I wrote a script to do ping test and awk the syslog for error and run it every 20 mins.

If a ping fails or an error if found in the syslog an email is sent

eg.

Code: Select all

#!/bin/bash

#set IP address
monitor1=192.168.1.100
#ping test
monitor1_chck=$(ping -c 1 $monitor1 | grep bytes | wc -l)
#write text depending on ping test
[ $monitor1_chck -gt 1 ] &&  monitor1_txt="UP" || monitor1_txt="Down" 
#check syslog for errors
m1=$(tail -n 500 /var/log/syslog | sort -r | awk '/ERR \[zmc_m1\] \[Failed to prime | ERR \[zmc_m1\] \[Unable to/ {print $7; exit}')
# write txt depending of syslog check result
[ "$m1" = "[zmc_m1]" ] && m1txt="Failed" || m1txt="Working"

#make table of results
resultstable() {

echo -e "  Name \t\t Capture\t IP Address\tStatus"
echo "------------------------------------------------------"
echo -e "monitor1 \t" $m1txt "\t"$parking" \t"$monitor1_txt 

}


#do check to sent email
if 
[ "$m1" = "[zmc_m1]" ] || [ $monitor1_chck -eq 1 ] 
then
resultstable | mail -s "Zoneminder Monitor OR ping Failed" user@gmail.com
fi

You need to have email send capability already set up

the tail n -500 limits the syslog to last 500 lines about 4 mins time

Thanks for that, anyway through zoneminder the thing can be achieved ?

Couldnt find a filter for that so I wrote the script.

Was planing on auto setting monitor to none but http call dont work and hadnt had time to look into the API calls

I did it with a custom config file for rsyslog and a cron script:

01-custom.conf on /etc/rsyslog.d/01-custom-conf

Code: Select all

if $msg contains "Shared data not" then /var/log/zm/lost-signal.log
if $msg contains "Unable to open input" then /var/log/zm/lost-signal.log

/etc/crontab

Code: Select all

*/2 * * * * root /scripts/check-segnale-telecamere.sh >/dev/null 2>&1

/scripts/check-segnale-telecamere.sh

Code: Select all
